An U.S. law enforcement official says a grenade found near the site where President Bush spoke in Tblisi, Georgia last week was capable of exploding.
The statement Wednesday from FBI agent Brian Parmen contradicts initial reports from Georgian officials who said the grenade was inactive.
Mr. Parmen says the grenade presented a threat to President Bush, Georgian President Mikhail Saakashvili, and the tens of thousands of Georgians who attended the May 10 speech in Tblisi's Freedom Square.
He says the grenade failed to explode only because of a malfunction with the triggering device.
Officials in the former Soviet republic have offered an $11,000 reward for information about how the grenade ended up at the site.
